[The action of fenigidin (nifedipine) on central hemodynamics and cerebral blood flow in hypertension].

Nifedipine is an effective agent in hypertensive emergencies as well as in the long-term management of hypertension especially for the patients with an increased risk of cerebral hypoperfusion. Nifedipine exerts its blood lowering effect by reducing total peripheral resistance including cerebrovascular resistance. Despite the marked reduction of perfusion pressure, the cerebral blood flow is maintained by nifedipine.
